the letter is how far we sit from the market, not how sure we are
THE PICTURE — what's driving the 2-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read
The home starter strikes out 16.5% of batters, adjusted — a lower strikeout rate than averageagainst the under42%
The home team below league average in home runs, last 30 games26%
The away team allowing 5 runs a game, last 30 — above league average. Priced in, and it went too far — counts toward the under12%
Umpire's strike zone has run narrower than the league this past year — fewer called strikesagainst the under12%
Backup catcher starting8%
Market: First-5-innings Under 4.5 at +101 (pinnacle, quoted 11:00 AM CDT) · the full picture prices it +106 · model expects ~5.4 runs · divergence 2 points — band none.
SITUATIONAL CONDITIONSdetected for this game · not a grade input — anything that carries weight appears in THE PICTURE
Heavily used bullpenCatcher rest spotSeptember call-up lineupDay game after a night gameGetaway day (day game, then travel)
Honest row: grades cap at the band — extreme disagreement is as often our error as the market's. Moneyline gets no grade because our model hasn't beaten that market and says so. Graded against the line at grade time; the model was validated against closing lines. Weather from forecast; regrade if conditions flip. F5 grades ride a shorter history (2023-2025).
